This part does not affect the base vehicle warranty.
The mountune Performance Cat-Back Exhaust reduces back-pressure and improves performance whilst keeping cabin intrusion / boom to a minimum.
A Helmholtz chamber design is utilised in the rear silencer which helps cancel out unwanted frequencies due to the way in which the exhaust gas waves are reflected. Utilising this system, despite being more complicated and expensive to manufacturer, ensures back-pressure remains low, providing the optimum in terms of performance, whilst removing as many of the unwanted frequencies / cabin boom as possible.
The staggered tail-pipe trim adds to the occasion and both trims feature laser-etched 'mountune' logos.
As a mountune Performance product, it's also the only cat-back exhaust available for your Fiesta ST that will not affect the base vehicle warranty and comes with a limited lifetime warranty against manufacturing defects.
Compatible with all 3-door models globally and EU-only 5-door models.
Customers in the USA please note there is a 5-door specific version, available at www.mountuneusa.com.

5 star product and 5 star service!! This is the second time I have been back to mountune after getting the 215 upgrade for my fiesta st (which I highly recommend) and now with the added cat back exhaust it tops it off - how the car should have left the factory! Brilliant noise without being intrusive in the cabin! HIGHLY RECOMMEND!
First time at Mountune HQ and was a great experience everyone is so friendly and well looked after by Ryan. Exhaust sounds awesome wish I’d done it along time ago great addition to go alongside the MP215 that I already had on the car. I shall be back soon I reckon for more upgrades!!!
Great service from Ryan exhaust sounds like how it should have been from stock up grade to the 215 is awesome power is there when you need it .lower spoiler looks good except that you can still see the colour of the car under the back of the spoiler but still happy with it
